Hey. I just got new audio interface UR 22 Steinberg and I have a problem. When I play through it, my Music Man SUB ray 4 sounds distorted when I play hard or when I slap. It's weird, because when I play through my amp or combo, it sounds just fine. I've heard people complaining about SUB output being too hot (and I agree) but... could this be causing the problem? Should I try to change the volume pot? Or is this caused by battery? I don't have any other bass to try on it, so I don't really know if it's caused by my bass or by the audio interface. Sorry for my english and thanks for any advices!
